Low-pressure Filter Backwash Recovery In Daqing Oil Field Water Treatment

Oilfield Produced Water for the amount of polymer increased dramatically, resulting in filtered water quality standards are not the problem, according to Ergun and Susumu Kawamuru theory, involving a new low-pressure backwash filter, it has not damaged the low pressure sieve, stirring anti-laundering the effect of good advantages. At the same time,designed to meet the requirements of supporting the new process, the application of the heating technology backwashing, backwashing gas technology, microflocculation Dosing technology, cans, etc. backwashing method group, the paper on low-voltage filter backwashing specific application in the field do specific and detailed analysis and elaboration.Eventually come to the conclusion and recommendations.
